Hardware Support
,
1

System Details

  • Device: Awasuki
  • OS: Zorin OS 18.1 Core
  • Firmware Type: UEFI Full ROM
  • Firmware Version: MrChromebox-2603.2
  • Internal storage type:

Summary of the Issue

No sound after install

Steps to Reproduce

  1. Fresh install
  2. Run audio fix script, no errors
  3. Only dummy audio detected

Expected Behavior

Detect correct drivers and play audio

Replaced ChromeOS with Zorin. I’ve tried so many suggestions I can’t even remember. No Idea if anything made it better or worse.

Hi and welcome.

Zorin 18 is based on Ubuntu 24.04 so I used it in my search criteria using Brave search engine via Mojeek search engine. Brave A.I. results in:

" For Chromebooks with Intel ICL (or similar SOF audio controllers) running Ubuntu 24.04 , audio is typically enabled by installing the SOF firmware and configuring the DSP driver .

1. Install SOF Firmware

The kernel module sof-audio-pci-intel-icl requires specific firmware blobs which are not always installed by default. Install the firmware-sof-signed package:

sudo apt update
sudo apt install firmware-sof-signed

2. Configure DSP Driver

If audio still does not work after installing the firmware, you may need to force the kernel to use the correct DSP driver. Create or edit the modprobe configuration file:

sudo nano /etc/modprobe.d/audio.conf

Add the following line to the file:

options snd-intel-dspconfig dsp_driver=3

Save the file and reboot the system.

3. Verify and Configure Output

After rebooting, verify that the sound card is detected:

aplay -l

If the internal speakers or headphones are not automatically detected (common on some models like the Samsung Chromebook Sasukette ), use PulseAudio Volume Control (pavucontrol ) to manually select the correct output profile (e.g., Pro Audio ) and sink. For persistent headphone jack detection issues, community scripts like linux-front-audio-fix may be required to force a headphone sink.

AI-generated answer. Please verify critical facts."

Welcome to the Forum!

Are Secure Boot and Fast Boot in BIOS disabled? Did You tried Pulse Audio Volume Control? It is a Tool to set up Ausio Input and Output. You can install it with sudo apt install pavucontrol via Terminal.

When installed, check the Configuration and Output Tab's for Audio Options and Profiles.

4

Did you make any edits to your grub file, for example acpi=off to get past a black screen hang or something? I had that and it was preventing binding the driver to my Tiger Lake sound card. acpi=noirq was the solution.

I already have firmware-sof-signed and it's still not recognizing soundcard after adding the suggested line.

sudo apt install firmware-sof-signed

I see that
snd_hda_intel 65536 0
and
snd_sof_pci_intel_icl 12288 0
must be where the problem is but can't figure out the fix.

I'm not sure how to access BIOS, I only have UEFI. I have Pulse Audio as well and it only shows Dummy Output.

My only issues were with audio and the touch pad so I don't thing anything I did involved acpi=off .

8

Did you follow Step 2. of ny post on configuring the DSP driver?

9

Yes, it's still not recognizing soundcard after adding the suggested line.

10

Hi, please open a terminal and enter:

sudo nano /proc/asound/modules

and post back the results please.

11

I did a fresh install last night to start clean after all the previous fixes I had attempted from posts I saw online and redid your suggestions but it's still not being recognized.
The result from the command you just requested is a blank window, the module as nothing on it.

12

what does sudo lshw -C multimedia show?

13

I noticed you have the sof-audio-pci-intel-ici driver. My similar card has the snd_hda_intel driver so I asked Brave AI what was the best driver for your card and got the following response:

The best driver for the Intel Jasper Lake sound card in Zorin OS 18.1 is the snd_hda_intel driver, as the default sof-audio-pci-intel-icl driver often causes "Dummy Output" issues.

Might be worth try changing. Again from Brave AI:

To force this driver, add snd-intel-dspcfg.dsp_driver=1 to the GRUB_CMDLINE_LINUX_DEFAULT line in /etc/default/grub , then run sudo update-grub and reboot. Alternatively, booting into an older kernel (such as 6.8 ) during the upgrade process may also allow the system to correctly identify the card using the snd_hda_intel driver.

And, yes, I do use the older 6.8 kernel because a couple of things didn't work in the default kernel.

Hope this helps.

On this help site are some informations what you can try when you get a dummy output:

15

I was originally trying to get it work with the snd-hda-intel driver but was having any success so that's why I tried going with sof-audio-pci-intel-icl and when that didn't work i decided to just restart from 0. I didn't have any success after adding the suggested line to grub but after switching to 6.8 at least now the soundcard is being recognized.

Pulse Audio still only shows Dummy Audio though.

16

Other users have had success using a more recent distribution and then running a Linux audio script for Chromebooks to get the sound working.

If nothing else works, you could try that.

That's how I ended up here. I was running the newest kernel Zorin pushed and already used that WeirdTreeThing script as instructed by the Chrultrabook

18

You probably need a non-LTS distribution to get the script to work.

19

I did some research using Brave search engine about whether Q4OS has been deployed in the Enterprise arena. Whilst no specific details of where such undertakings were made reference was made to a Library that had 300 Chromebooks that needed saving from landfill and Q4OS was the only distribution that installed without issue. Bearing in mind that these were for a Library, no guarantee that sound would be present!

5.9 is good until June 2028.
